To all whom "it may concern Be it known that I, FREDERICK J; LooMIs,

a citizen of the United States, residing at:

V for Shaping Heated Metal; and I dohereby declare the followingto be a full, clear, and

exact description 'of'the invention, such asv will enable others skilled inthe art to which it appertains to make and use the same.

This invention relates to improvements in apparatus for shaping heated metal under pressure, and it consistsin the productionv of a container having the usual inner tube and particularly constructed pressure resisting means surroundingthe same. These means ing a suitableinsulator. A detachable casing formed in sections surrounds the flanged. cylinders and isprovided with fastening de-.

vices, the sections of thefcasing and the segments of the flanged cylinders being arranged in suchmanner that the joints in the respective'cylinders. and in the casing do not coincide. I I j In the accompanying drawingsFigure 1 is a perspective view ofthe'device, the ends of the cylinders being. out off approximately on the line 22 of Fig. 2, in order to show the insulating material. I Fig. 2 is a horizontal longitudinal section of the device. Fig.3 is a section of Fig. 2 on the line 2- 2. r

In the constructionof devices of" this char ments in. such manner that they [will resist in the best possible way the strains exerted upon them. i

In carrying'out my invention I provide a central tube 1 having an offset portion 2 to prevent it from being forced from the sur-l rounding reinforcing means. Enclrcling the tube 1 is a heat insulator 3 of any desirable material. This insulator extends to: within a short distance ofeach endiofthe container;

Surrounding the insulating materialis a cylinder t, preferably made 111 two' sections having tongue and groove joints 5,5. This cylinder is made with a hollowed out portlon 6 to accommodatev the insulating material,

and a similar hollowed out portion-or annu lar recess" 7 accommodatesv a cylinder 8, formed in sections,and'preferably provided I j withtongue andgroove joints. The cylinder 4 has therefore outwardly and inwardly pro ecting flanges 9 and 10, the inner flanges being thicker. than the outer flanges, as

shown. This construction enables the device to resist a great amount of pressure at the-ends. j

9 Surrounding the cylinder 8 is an outer cylinder 18 formed with a projecting ridge 11 adapted to fit into a cut-out portion 12 of the cylinder 8. The cylinder 13 is made in sections in order that it may be easily removed when desired, and the sections are provided with lips 14 and 15 adapted to be secured together by means of bolts 16 and 17. The contacting edges of the sections of cylinder 13 havetongue and groove connections 18 and 19. The cylinders 4:, 8 and 13 are preferably arranged so that-the edges of the sections of adjoining cylinders do not coin- The principal reason for providing the several concentric cylinders formed in sections is that the apparatus may have the strength of asingle cylinder of equal thickness and yet permit of the easy renewal of any part which may become worn or broken. It is obvious that the insulating material maybe formed in sections also, and that other changes coming within the scope of my invention may be 1n de.

' What I claim as new, and desire to secure by LettersPatent, is

A device of the class described, comprising tube, a cylinder formed in segments surroundingsaid tube and provided on each end with-internal and external flanges, the inner flanges thicker than the external flanges and bearing against the tube, insulating material betweensaid tube and cylinder, a second segmental cylinder provided with an offset portion on its ends and surrounding the cylinder last mentioned, the offset portion'engaging the flanges of the flanged cylinder, and a detachable casing engaging anannular recess in the second cylinder.

In testimony whereof I aflix my signature in presence of two witnesses.
